Be it known that I, ROBERT Gr BABcocK, of New London, in the county of New London and State of Connecticut, have invented anew. and Improved Machine for Bending,

Drawing, and Chamfering `I-lor-seshoes; and

`I do hereby declare :the followingto be a full, clear, and exact description of 'the same', reference being had to the accompanying t drawings, maklng i a part thereof, in which-9 t, t o

"Figure l, represents a top view,`with the topjplate removed# Fig.2,` represents a lon-` gitudinal vertical section through the ma-` chine. i t d t lSimilar letters in the severa-l figures represent the same parts.

' The nature of my invention consistsfinj bending, drawing and charnfering i horse shoes at thesameoperation, themachine be-` ing so adjustable as to be adapted fformaking larger orsmaller shoes, and `the draft of the shoe from toe to heel be drawn out by a patterntoany form desired. t i

" To enable others skilled in the artto make and use my invention, I will proceed to de-` scribe the same with reference tothe draw-` 1n s;

one end of a substantial wooden frame A, firmly bolted to a stone foundation,`are placed the boXesB B, resting and turning in which, on its journals, is the shaft C. Uponsaid `shaft C, is placed the pulley D, over which the band that drives the machine may pass, and on thefend of said shaft out side of the frame is placed the balance wheel E, on said shaft is also t placed the spur wheel F, which meshes into a cog wheel G, which is placed on a shaft H, which has its bearings in the, pillar blocks I, said pillar blocks being firmly secured `to the frame aforesaid. "Uponthe end-of the shaft H, is laced the crank `J ,which plays between the lbhgitudinal timbers of the frame," To` a wrist on said crank J, is attached a connecting rod K, the other end ofwhich said con-` neeting rod is attached tota cross head L,;to

d be hereafter described, On the other endof the framel is arranged the bed plate` M, on whichfthe machinery is erected. On said bedplate, are cast; the ways c, c, which have angular vprojectionthereon on their inside,

IThearm's o drawing roller 10, inthe `lower projection,

and the shafts Qc, of theguide rollers P, "1?, in their lupper projegtjon i i A f i "Supported on the uprights Q, whichfare firmly secured to the bed plate,is a plate `or t cap `piece R, which `is made adjustable by means of the screw nuts f, both above and below said cap` piece, which said nuts fit onto screws cut on the upper ends ofthe ternsg, for drawing the horse shoe by, and

head advances, run upon the wedge-shaped pieces or patterns vg, and guide the drawing roller O, allowing said drawing roller` to rise or fall as it advances` upon"`the horse aforesaid uprights Q, `Sliding in grooves o made in flanges on theundersideof said cap piece R,"arefwedge shaped pieces or patg` shoe, and giving said shoe'the desired draft ,t

from toe` to heel. By substituting for the drawing roller herein described, yother proper shaped rollers, and forwthe wedge shaped pattern, other suitablepatterna I am enabled "to draw out ax-skelps, block hooks, and many `otherirregular forms,and

forwhich purpose, I intendalso to apply my machine` o t t t Instead of the guide,` rollers farrangedas herein described, they maybe made larger,- and placed on the sameshaft with the draw-` ing roller, andrun in groovesor guide pieces inthe bed plate, and inlwhichlatter position I may use them if found essential. t ,t t In a socket S, cast on the opposite end of rod is attached to it, is inserted the tang It, of a fork-shaped piece `T,s`aid piece being made adjustable in the socket v,ofthe cross fthe cross head from wherethetconnectingl head, by means of a setscrew z', and, when y d T the Vformer U,'and bending said blank into y, run out so that the shoulder on Said forkshaped piece T, does not rest against the shoulder of the socket, a washer may be placed `on the tang, so as to Ygive it sufcient strengthto accomplish its intended object. The jaws lc, of the kfork-shaped piece T extend forward of theV drawing roller O, and

on the underside, in the extreme ends of the inside of said jaws 7c, are placed the pins Z, Zfor catching the blank on each sidevof the heel.

j In the bed, plate is fixed a mold of steel n, which rests upon a plate 0, extending across the longitudinal pieces of the frame under thebed plate. In a suitable hole in this mold is placed the-former U, which stands upisufficiently Vhigh above the bed plate to catch'they blank, as itis forced up against said Iformer by the ins Z Z, the lower end of said former resting upon a spring p, which as the drawing roller O, comes upon said former, allows it toV sink, leaving the wholev pressure of the drawing roller upon the' shoe, and after the roller has passed, the spring p, immediately raises the former j in proper position for the next operation.

To prevent the former from being clogged by the cinder from the iron, I sometimes place a light trip hammer below it, worked V cams on the cross head, or other moving part'o'f the machinery, so as to strike the i former a slight blow, every time the draw roller passes over the said former, so as to' insure its being in proper place for catching the nextl blank.

Extending from the front of the former, to the Vend of the bed plate, and attached to said bed plate, is the gage plate V, upon which the draw roller runs after passing over the shoe the top of said gage plate being on the same plane with the top of the shoe, so as to give time for the chamferingvtool to' come up and perform its operation, said gage plate V, holding the draw roller 'uptothe height of the shoe so that in returning it may not drag back the shoe from the former, but pass over it again to smooth down the feathered edges `caused by they chamfering tool, and where said gage plate joins the former, it is slightly sloped off so as to chamfer the toes of the shoe from inside to outside. v y

"On the extreme end of the bed plate is ar- 'put into Vused 'may' ranged, a friction and pressing roller W, supported by its journals in the studs X, and at such height above the bed plate, as to allow the points of the jaws Zt, which are sloped oflI for that purpose to pass under, for the purpose of holding down the fork shaped piece T, while chamfering the shoe. By having sets of formers, and fork shaped pieces, and which are readily taken out and lace, the various sizes of shoes e made on Vone machine. t t i Attached to one of the ways which guide the cross head, is a crooked lever Y, which is struck by the cross head as it moves back and forth, and gives it a vibratory motion. On a pin on the eXtreme end of said lever Y, is arranged a hinged arm g, which at the proper intervals forces the blank intoV proper position for being caught and bent. On the bed plate, or a projection thereof are placed the guides 1" r, between which the blank is placed, and between which guides the arm g, on the end of the vibrating lever aforesaid, also moves, forcing up the blank into its proper place. On the opposite way, is arranged another and similar lever Z, and

which is also operated by the cross head.

being heated and pushed into proper position, is caught by the pins in the ends of the jaws of the fork shaped piece, and forced up against the former where it is caught, the jaws moving on bend the ends of the blank round the former. The drawing roller then strikes the shoe and by means of the pattern by which it is guided, draws the shoe on top to the proper taper, the jaws drawing out the heel part of the shoe against the sides of the gage V, until the rear of the jaw advances, and chamfers the shoe, the roller having passed on to the gage plate in advance of the shoe. As the cross head is drawn back the roller presses down any feathered edge left on the shoe in chamfering, and the pins in the end of the jaws, as they are drawn back with the cross head, catches against the shoe, and carries it back from the former, when it drops through an opening in the bed plate, and between the longitudinal ieces of the frame into a conveyance whic caries it to the swaging and punching machine. And as soon as the roller passes back over the former, it (the upon which it rests, immediately into position for receiving the next blank.

` Having thus fully described my invention and smooth down the feathered edges raised what I claim therein as new and desire to by the chaxnfering tool as herein described 10 secIure bybLetteI-s Patlnt is 1 and represented.
